carina, Which appears double at the summit, and slightly nodulous 
where it is crossed by the longitudinal lines. Above the ‘carina 
there is a rather wide, sloping, flattened or slightly concave sub- 
sutural band, which is crossed by somewhat raised, moderately 
excurved lamella, parallel with the lines of growth and with the 
sinus in the lip; there is also a rather faint revolving cingulus a little 
below the middle of the band. Below the principal carina there is 
a rather wide concave interspace, which surrounds the middle or 
most prominent part of the whorls, and is bounded below by a carina 
like the upper one, but not quite so strong; anterior to this there 
are, on the body-whorl and siphon, numerous similar double revolv- 
ing cinguli, decreasing in size and becoming closer anteriorly; of 
these there are about twelve above the base of the siphon; the con- 
cave interspaces between the upper ones are about equal in width to 
the cinguli. The whole surface is covered by numerous slightly 
raised, longitudinal lines, which are parallel with the lines of growth 
and are most conspicuous in the interspaces between the cinguli. 
The apex, in our single specimen, is badly eroded. The aperture is 
narrow-ovate, not very large, with a distinct obtuse angle at the base 
of the columella, which is rather short and nearly straight. The 
siphon is short and straight, distinguished from the body-whorl only 
by a slight undulation. The canal is short, straight and rather open. 
Length, without the nuclear whorls, 27""; breadth, 13"; length 
of aperture, 13™"; its breadth, 5™™. 
Station 2105, off Chesapeake Bay, in 1395 fathoms (No. 35,704), 
one dead specimen. 
The single specimen of this species is considerably eroded, so that 
the sculpture, especially the longitudinal lines, appears more strongly 
marked than it would in a fresh specimen. Perhaps the double 
character of the revolving carinze is more obvious for the same 
reason. They may originally have been more elevated and sharper. 
The species bears but little resemblance to any other known from 
our coast, but the character of the sculpture is not unlike B. bicari- 
nata, but the largest specimens of the latter are pygmies, in com- 
parison with the present species. 
Urosalpinx Carolinensis Verrill, sp. nov. 
Shell small, pretty regularly fusiform, with an elevated, rather 
acute spire, which forms nearly one-half the total length of the shell. 
Whorls six to seven moderately convex, with an impressed suture. 
The sculpture consists of about twelve rather prominent, stout longi-
